From the Mariana Trench, the deepest point on earth, to surging shorelines and anywhere in-between, we make the impossible possible through our continuous passion for innovation.

Our people design, engineer and manufacture technologies that are enabling our customers to discover, navigate, measure, detect and communicate in the toughest environment on earth: Our oceans. We’ve been actively developing the technology to make the oceans accessible for over 50 years and we’re only just getting started… At Sonardyne, we value different ways of thinking. Whether you think in code, patterns, systems, or steps, your unique perspective is important to us.

Sonardyne is seeking a detail-oriented and motivated Transducer Test Engineer to join our Electromechanical Design Group. This is a hands-on, varied role supporting both existing underwater acoustic products and calibration equipment used across our UK and international operations.

With over 50 years of expertise in underwater acoustics, Sonardyne offers a unique opportunity to work on innovative transducer technologies while learning from and collaborating with experienced engineers and production specialists. We welcome applicants from all backgrounds who are eager to learn, contribute, and grow within a collaborative engineering environment.

About the Role

Reporting to the Senior Transducer Engineer, you will play a key role in testing, analysing, and improving underwater acoustic transducer systems. The role involves both laboratory-based work and close collaboration with production and engineering teams.

If you join you will:

• Perform in-air and in-water acoustic and electrical testing

• Analyse test data and produce clear technical reports, including root cause analysis and recommendations

• Use specialised laboratory equipment to measure sound pressure levels, frequency response, noise, and vibration

• Develop and execute test procedures that meet acoustic, electrical, and environmental standards

• Support and improve existing underwater acoustic products and calibration systems

• Communicate results clearly through written reports and technical presentations

• Liaise with production teams to improve acoustic processes and implement enhancements

• Assist with the development and evaluation of new subsea transducer designs

• Ensure compliance with relevant industry standards, regulations, and certifications

About You :

You are analytical, methodical, and enjoy hands-on engineering work. You take pride in producing high-quality results and communicating clearly with both technical and non-technical audiences.

Ideally we would like:

• Strong problem-solving ability with excellent attention to detail

• Knowledge or interest in underwater acoustics

• Clear and effective written communication skills

• Understanding of transducer and electrical engineering fundamentals

• Strong IT skills, particularly Microsoft Office

• Degree in Physics, Mathematics, or Engineering (or equivalent)

It would be a bonus if you had:

• Experience developing laboratory software and test tools

• Practical mechanical engineering skills, including prototype assembly and testing

• Experience working within quality-controlled or regulated environments

Why Join Sonardyne?

• Work with cutting-edge underwater acoustic technology

• Learn from industry-leading experts

• Be part of a collaborative and inclusive engineering culture

• Contribute to products used globally across renewables, offshore energy, science, autonomous systems, and defence
